Scriba Creek is eighteen miles long and is a large, clear, 
rapid flowing stream emptying into Oneida Lake at the vil- 
lage of Constantia. Its headwaters rise in the Town of 
Amboy. At its mouth it is upward of 6 feet in depth, and 
the bottom is sandy; north of the bridge, and above the june- 
tion of Frederick Creek, the bottom is very rocky, the eur- 
rent swift and the water shallow (6 to 15 inches deep). 
Beneath the rocks and clinging to them occur a number of 
forms of life, as noted below, which form desirable food for 
the fish in the stream.
